METALLIC ROOF.

SPECIFICATION `forming part of Letters Patent No. 537,569, dated April 16, 1895.

` Application filed May '7, 1894. Serial No. 510,359 (No specimens.)

.To all whom t 'may concern:

Be it known that I, LOUISv S. FLATAU, a citizen ofthe United States, and a resident of Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Metallic Roofs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make 'and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in metallic roong and its object is to provide an improved means for securing the adjoining edges of the metallic strips together, whereby a tight water proof joint is produced andthe metal strips securely attached to the `sheathing of the roof.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a perspective view of a section of a roof constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the same. Figs. 3 and 4 are detail sectional views showing different steps in forming the joints or seams. Fig. 5 is a detail perspective view partly broken away' showing the seam before being iiattened or pressed down.

In the said drawings the reference numeral 1 designates the sheathing of a roof, which may be of any ordinary or suitable construction.

The numeral 2 designates the metallic roofing or covering sheets, laid side by side as usual, and extending from the eaves to the upper end of the roof. The adjoining edges of these sheets are turned upwardly and backwardly forming wings 3, between which is inserted a rope 4, preferably tarred, for a purpose hereinafter describedu The numeral 5 designates a cover, or covers, consisting of a metallic plate having itsedges bent downwardly and inwardly forming flanges 6, which engage under the wings 3 of the covering sheets. At suitable points along the length of these covers nails 7 are driven which pass therethrough and through the rope packing interposedA between the edges of the sheets, into the sheathing beneath. Protecting caps 8 consisting of sheet metal plates having their edges bent downwardly and inwardly forming fianges 9 are then placed over the covers 5, the side (langes engaging under the flanges 6, covering and protecting the nails 7, and preventing entrance of water through the apertures through which they pass. They also serve to stiften and strengthen the seam or joint.` The ends of these caps 8, at the ridge and eave of the roof are bent downwardly at an angle and secured to the sheathing or rafters, by means of nails or spikes l0, thus forming additional means for-securing the covering sheets in place.

In constructing a roof according to my invention, the metallic sheets are laid on the sheathing, extending from the ridge to the eave, or from eave to eave when the roof is an oval one and the adjoining edges turned over forming the wings 3. The tarred rope is then inserted between the said sheets, the covers 5 engaged with the said wings and the nails '7 driven through the covers and rope. The caps 8 are then placedv in position and the seam thus formed is liattened by means of rollers pressed thereon or by hammering so as to drive the nails into the roof andmake a water tight joint and finally the ends of the caps are bent downwardly and nailed to the sheathing or rafters.

The tarred rope 4, may be dispensed with if desired, it being intendedmore especially for use in roofs which are subjected to frequent and severe snow storms, to prevent the possibility of leakage of the joints or seams.

My invention is applicable for use on build ings generally, but is more especially designed for rooting box and other cars, the seam in this case, running over the center of the car from end to end thereof. In case of an oval roof there need be no center seam.

The invention can also be used as a wall or weather boarding for buildings, by setting the sheets vertically and securing them by means of the seams described to suitable studding.

Having thus fully described my invention, what I claim is- 1. In armetallic roof the combination with the covering sheets having their adjoining edges turned upwardly and backwardly forming wings, the covers consisting of metal plates having their edges bent downwardly and inwardly forming flanges engaging under said wings and the nails passing through apertures in said covers and between said sheets into the sheathing, of the caps consisting of the metal plates having their edges bent downwardly and inwardly and engaging under the flanges of the covers, and the seam thus formed flattened or pressed down to drive the nails into the roof and make a water tight joint, and the ends of the caps bent downwardly and secured tothe roof; substantially as and for the purpose specified.

2. In a metallic roof, the combination with the covering sheets having their adjoining edgesturned upwardly and backwardly forming wings, the packing rope inserted between said sheets, the covers consisting of metal plates having their edges turned upwardly and backwardly and engaging under` said wings and the nails passing through said covers and rope into the sheathing, of the caps consisting of the metal plates having their edges turned downwardly4 and inwardly and engaging under the flanges of said covers and their ends bent downwardly and secured to the roof; substantially as and for the purpose specified.

3. The method herein described of constructing metallic roofs consisting of the following steps, viz: first turning the adjoining edges of the covering sheets upwardly and backwardly, then engaging the covers therewith and nailing the same to the sheathing, then applying the protecting caps, then flattening or pressing down the seam thus formed to drive the nails home and make a water tight joint and finally bending the ends of said caps downwardly and nailing to the roof; substantially as specified.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

LOUIS S. FLATAU.
